I have recently been working on extracting all the co-ordinates of genes which are regulated by p53 transcription factor and have obtained a list of genes from a research paper. now i need to find out the coordinates of the start and end of these list of genes in the genome from the table browser so that i can do some further analysis . is there a way I can obtain the start and end co-ordinates of these genes.

PS: by start and end co-ordinates i meant the start and end coordinates of the first exon as there can be multiple exons of the same gene
